When to Use Your Pool Closing Checklist Connecticut Guide
Close your pool before overnight temperatures drop below 32 degrees Fahrenheit consistently, typically mid-October in Fairfield County and Westchester County. Waiting too long risks a freeze event catching you off guard.
Water Chemistry: One Week Before Closing
- Test and balance pH to 7.2 to 7.6
- Adjust total alkalinity to 80 to 120 ppm
- Shock the pool with a high dose of chlorine
- Add winter algaecide per label directions
- Add a metal sequestrant if your water has iron or copper
Equipment Shutdown
- Turn off and unplug the pump, filter, heater, and automation system
- Drain water from the pump, filter, heater, and chlorinator
- Remove and store the pump strainer basket and cartridge filter elements
- Backwash DE or sand filters and drain completely
- Remove and store any in-line chlorinators or salt cells
Blowing Out the Plumbing Lines
- Lower water level 12 to 18 inches below the skimmer for mesh covers
- Blow out all return lines, skimmer lines, and main drain lines with a blower
- Install winter plugs in all returns, skimmer, and main drain
- Verify all plugs are seated. Water in any line will freeze and crack it.
Accessories and Cover
- Add water tubes or cover anchors to keep the cover secure through winter storms
